Apple Cake with Streusel topping

Hooray atlast i baked a cake. This is my long time dream.My mom used to bake cake for christmas at home.After seeing all the baking in the blogs, i wanted to try...........but never attempted. Recently one of my friend baked a cake for her hubbys b'day and even in her first try it came out gr8. From then onwards my dream became my obsession and atlast it got satisfied.

 This recipe is Laura s. From the day 1 i  saw this recipe i wanted to give a try. I followed the same recipe. But i added extra egg and milk, since using the original recipe i found the batter little thick.
